Working Principles

The NJM79M06FA is a monolithic 3-terminal negative voltage regulator. It utilizes a series pass transistor to regulate the output voltage. The input voltage is stepped down to the desired -6V output voltage by dissipating excess energy as heat. The regulator maintains a stable output voltage by adjusting the resistance between the input and output pins.
